In Minneapolis, MN, the typical last frost lands around May 5. Working back 4-6 weeks from transplant time gives you a seed-starting window of Mar 24 – Apr 7 indoors. Strawberry plants are tolerant of light frost, so they can go out Apr 14-May 12, even before the frost date.

Why
That leaves roughly 146 days of growing season before the typical first fall frost (Oct 5) — enough for most varieties. In a short-season area, favor early-maturing varieties (check the days-to-maturity on the tag).
- Frost kills tender seedlings outright, and cold soil stunts them even without frost — both dates matter.
- The 50% frost date is a planning midpoint: a late frost is still possible, so keep covers handy for the first two weeks.
When this doesn't apply
- Late summer to early autumn planting also works (RHS) — those plants establish before winter and fruit the following year. Set crowns level with the soil surface.
- Season extenders (row covers, walls of water, cold frames) let you plant 2-3 weeks earlier than these windows.
- Frost dates are area averages — low spots and valley floors run colder than the local average.
